ALIF requires a fellowship-trained spine surgeon, an access surgery colleague for vascular mobilization, and hospital infrastructure to support the anterior abdominal approach safely. POA offers ALIF through hospital facilities within our Southern New Jersey network, bringing complex lumbar reconstruction to patients who would otherwise need to travel to Philadelphia or a major academic center.
What is the difference between ALIF and TLIF?
ALIF approaches the lumbar disc from the front; TLIF approaches from the back. ALIF allows a larger cage, better lordosis correction, and avoids moving nerve roots, but requires an access surgeon for vascular mobilization and carries approach-specific risks. TLIF is a posterior-only procedure that does not require an access surgeon. The choice depends on the anatomy, levels involved, surgical history, and reconstruction goals.
Is ALIF riskier than other fusion approaches?
ALIF carries approach-specific risks from the anterior abdominal incision and vascular mobilization, including rare but serious risk of vascular injury and retrograde ejaculation in male patients. These risks are well-characterized, low in incidence in experienced hands, and are discussed thoroughly at your surgical consultation. In appropriately selected patients, the structural advantages of anterior reconstruction outweigh the approach-related risks.
How do I know if I am a candidate for ALIF versus posterior fusion?
ALIF is most advantageous at L5-S1 and for cases where anterior column reconstruction addresses a problem posterior technique cannot solve as effectively: significant lordosis loss, high-grade spondylolisthesis requiring reduction, or failed posterior fusion needing anterior column support. Your POA surgeon will review your imaging and explain specifically whether your anatomy warrants the anterior approach.
